I dug under the foundation and up into the crawl space started a 6 am. All hand digging in very hard clay. That was a pain in the butt it is done. I then mounted the manifold in the crawl space.
I have the first to loops done and the return lines staked 2’ up the trench. it was a muddy mess. They finished digging the trench so I can now install the next two loops then start back filling.
Water is about a foot deep in places.
I was dark when I finished so I did not get any pictures. I was a wet cold muddy mess. Red wet clay everywhere.
